First mech was a chi clone, hated it so much that I used my vtr until I bought my legit ar mod. This is when my sub ohming journey started, loved the ar/patriot combo then the spring broke and I used the spring out of my vamo (which is way to stiff) but I'm still getting getting the hot button. Ive cleaned it multiple times. Then I bought a "high quality" 26650 stingray clone with the magnet button with a 28mm tobh which is also a good quality clone. 3 weeks or so I've been using the stingray and the button is getting to where I can only hit it in a certain spot on the edges or it won't fire. I've taken it apart scotch padded and alcoholed the parts and put it back together and no luck. Blehhhh.
